Removal Procedure

The transaxle range switch contains four switches that ground four different circuits. These circuits are 771 (switch A), 772 (switch B), 773 (switch C), and 776 (switch D). The switch also contains the backup lamp switch and the neutral/start switch.

The transaxle monitors these four circuits and determines what gear the operator has selected by the combinations of opens and grounds. Each combination indicates a specific selection in the manual shift quadrant (PRND32).

Refer to chart for transaxle range switch in this manual for further information.
